Thanks for the comments Patrick, Gaia bothers me a bit. As you say, it may not be just "anthropomorphic babble", but it sounds a lot like it--especially if referred to as "she/her." Someone on the Friday group also mentioned Gaia. I had this to say.
As generally understood the Gaia hypothesis is taken to be a somewhat mystical mechanism. Wikipedia puts it as follows. The *Gaia hypothesis* is an ecological<http://en.wikipedia.org/wiki/Ecology> hypothesis <http://en.wikipedia.org/wiki/Hypothesis> proposing that the biosphere <http://en.wikipedia.org/wiki/Biosphere> and the physical components of the Earth <http://en.wikipedia.org/wiki/Earth> (atmosphere<http://en.wikipedia.org/wiki/Atmosphere>, cryosphere <http://en.wikipedia.org/wiki/Cryosphere>, hydrosphere<http://en.wikipedia.org/wiki/Hydrosphere>and lithosphere <http://en.wikipedia.org/wiki/Lithosphere>) are closely integrated to form a complex interacting system<http://en.wikipedia.org/wiki/Complex_system>that maintains the climatic <http://en.wikipedia.org/wiki/Climate>biogeochemical<http://en.wikipedia.org/wiki/Biogeochemistry>conditions on Earth in a preferred homeostasis <http://en.wikipedia.org/wiki/Homeostasis>. More dispassionately, I think of Gaia as a name used to refer to (some of) the homeostatic mechanisms that maintain conditions on earth within a fairly large basin of attraction that we find convenient. We are fortunate that such mechanisms have worked in the past. (Or if one wants to drag in the anthropic principle, if they hadn't we wouldn't be here to be grateful about it.) But I wouldn't reify those mechanisms as a sort of global consciousness as it often is. What I'm saying is that we must now start to be explicitly conscious about global conditions--and not just about ecological conditions but about social, economic, and political conditions as well. I'm less convinced that Gaia "will sort things out again after we have gone." Certainly the universe will continue after we've gone. But that's small comfort if one cares about this civilization. Look what happened to Venus--even without the "benefit" of human intervention. Is there really sound reason to believe that the same thing can't happen here? Homeostatic mechanisms can respond to only a limited range of disturbances. They won't always work--and once a system switches from one attractor to another it's hard to move back to the former one. -- Russ Abbott _____________________________________________ Professor, Computer Science California State University, Los Angeles Cell phone: 310-621-3805 o Check out my blog at http://russabbott.blogspot.com/ On Mon, Oct 5, 2009 at 7:19 AM, Patrick Beautement < patr...@abacipartners.co.uk> wrote: > Russ, > Yes, hence the value of James Lovelock's thinking of the Earth in terms he > characterised as "GAIA". > > At present, GAIA has the the flu, and 'her' high temperature may result in > 'her' immune system doing away with that nasty 'human' virus that is making > her so ill. > They, 'her' powerful homeostatic / autonomic processes, will sort things > out again after we have gone. > > This is not just anthropomorphic babble - behind Lovelock's 'theory' is > some really solid and elegant complexity science - just very much ahead of > its time. > If you haven't read his books, I recommend you do. > > You say "The global system is not just ecological.
